Description

When I try to run multiple dvc run commands, I get the following error:

$ dvc run ...
Failed to lock before running a command: Cannot perform the cmd since DVC is busy and locked. Please retry the cmd later.

This is inconvenient b/c I'd love to run multiple experiments together using dvc. Anyway we can be more smart about locking?

Research direction

Start by reproducing concurrent dvc run commands and reading the locking behavior around the dvc run entry point. Define how jobs should be scheduled and how locking should behave during parallel execution; done means multiple experiments can run together without the current busy-lock error.
